bodied in the claims Aim warren su mon f essui es-r V a'fciti zen of the United States, resid- Akron, in the "county of. Sumrnitand, State of Ohi o, hav e invented "a certain new and"useful Improvement in OilTndWater geparatorsmi which the following-L is a full,- iflea'r', and exact description, reterencefv being had to the accompanying drawings. My nvention relates to oil-and-water sepa- I le but eflective device of this kind'fthat wil I absolutely separate the oil and water and prevent any oil. (gasolene, naphtha, etc.,) from being discharged with the'water.

A further object of the invention is the prov sion of a self-containeddevice of this I H readily applied or connected to any convenient oil receptacle? A still further object'of the invention is to provide a device 'of'thi'scharacter that is 'adaptable to and 'equally'eflicient with differengine oil, naphtha,

Generally speaking, the invention may \be definedas consisting of the combination of "elements, for"the* urposes specified, em-a v ereto-annfexed."

With a relatively shallow receptacle, as shown in the drawing, the partition will extend nearly to a 5 the bottom. By observing that the top of 11 15" a, depth of about three inches of oil on top of the water in 2, the depth of oil varying with the gravity thereof. For very light or very heavy oils, the cup 11 may be adjustedto aet commodate the difference in the gravities thereof, but I have found the distance of =3" above the top of barrier 10 to accommodate all ordinary fluctuations in the gravities of the oils delivered into 2, (whether heavy oil, as engine oil, or light oil, as naphtha, gasolene, vetc.,)-without permitting any oil to pass below 4 and into 3. A

The use of the barrier 10 maintains a constant head of water in 3, independent of the rate of flow through the outlet 9. \Vith an outlet pipe leading from the side wall of compartment 3 and an irregular rate of flow "of oil and water into 2, it will be evident I that the level of the liquid in 3, and necessarily of that in 2, will fluctuate, making it escape of water with the oil discharged through 11. The barrier 10, however, provides an extended trough communicating with 9 which will accommodate any unusual 40 overflow of water from 10, dueto gushes in the sunol through theinlet- 7, without any danger o backing up andvarying the level of the water in 3. a

The inlet 7 should be located considerably above the bottom of the partition 4, espec'ially when provided with a- 'downturned discharge end, to prevent any mingled oil and water: from tion. To render 1t impossible for oil to pass under 4, due to the pressure under which oil and water may be supplied through the inlet 7, I may interpose a barrier 16 between the inlet and the bottom of the partition 4. This barrier is located adjacent the partition 4,

. projecting upwardly from the bottom of the.

rece tacle. and extending transversely thereof, avin the ends attached to the side walls of t e rece tacle, as by side flan es 17 united thereto. hould the head or force of inflow through 7 be sufiicient to carry any oil down toward the bottom of the receptacle and toward the passageway 63, the barrier 16 willdeflect'the same upwardly and -thus' prevent it from passing into the compertinent 3.

difiicult, if not impossible, to prevent the assing beneath the parti- The embodiment of my invention herein set forth will automatically and absolutely separate the oil and -water and will permit only water unmingled with oil to flow from outlet 9. This is of great importance, as many cities have stringent regulations against discharging oil into their sewer systems. By my invention, however, the outlet 9 may discharge into a sewer without any danger of carrying oil thereto.
